1 INTRODUCTION

1.1 Background 1.1.1 Further to the Final TIA Report submitted via Hong Kong Housing Authority (HKHA) memo dated 15 October 2018 and Transport Department’s acceptance memo on 2 November 2018, Arup was appointed by HKHA to update the TIA report to reflect the latest updates on the facilities and population intake years provided of the proposed public housing development at Sites 1 and 2 in Sheung Shui Areas 4 and 30 (the Sites). Sites 1 and 2 are public housing development at Choi Yuen Road and San Wan Road respectively. 1.1.2 Site 1 is bounded by Choi Fai Street on the north, Choi Yuen Road on the south and Po Shek Wu Road on the east. It is zoned “Industrial” (“I”) and currently an existing public car park under Short Term Tenancy (STT). The proposed public housing development will comprise of about 2,088 flats and is envisaged to be completed by Year 2025/26 for Phase 1 (2 residential blocks), Year 2027 for a new public transport interchange and Year 2029/30 for Phase 2 (1 residential block). The site location and its environs in the vicinity are shown in Figure 1. 1.1.3 Site 2 is bounded by Ka Fu Close on the north, San Wan Road on the south and Po Shek Wu Road on the east. It is zoned “I” and “Other Specified Uses” annotated (Bus Depot) (“OU (Bus Depot)”) and partly as an existing public car park under STT and partly as WSD’s depot under TGLA. The proposed public housing development will comprise of about 1,556 flats (3 residential blocks) and is envisaged to be completed by Year 2025/26. The site location and its environs in the vicinity are shown in Figure 1. 1.1.4 This TIA study is to examine the impacts of the traffic generated by the proposed public housing development at the Sites on the existing and planned road networks, particularly with respect to the performances of the affected junctions in the vicinity; and present the findings and results of analyses of the other traffic and transport issues related to the proposed public housing developments. Any deficiency would be identified and improvement proposals would be recommended if necessary to resolve any foreseeable problem.

1.2 Comparison of Development Plan of the Sites 1.2.1 According to the latest development plan provided by HKHA, the development parameter and population in take year of the proposed public housing development in the Sites has been updated. Table 1.1 below compares the development schedule (i.e. those adopted in the accepted TIA as abovementioned in para 1.1.1, and the latest development plan) of the proposed public housing developments in the Sites.

• Ka Fu Close Ka Fu Close is a single-two lane local distributor in the industrial area. It forms a local road network with other local roads, i.e. San Po Street and Cheuk Wan Street.

2.3 Existing Traffic Condition 2.3.1 To appreciate the existing traffic conditions, comprehensive classified traffic counts were conducted at the following key junctions and links. The assessments have been based on the latest junction layouts and method of control. Locations of these surveyed junctions and links are listed below and shown in Figure 1.

• J1 – Jockey Club Road / Po Shek Wu Road (Roundabout) • J2 – Po Shek Wu Road / Po Wan Road (Signal Junction) • J3 – Po Shek Wu Road / Choi Yuen Road (Signal Junction) • J4 – Choi Yuen Road / Pak Wo Road (Roundabout) • J5 – Jockey Club Road / Lung Sum Avenue (Signal Junction) • J6 – Jockey Club Road / So Kwun Po Road (Signal Junction) • J7 – So Kwun Po Road Interchange (Roundabout) • J8 – Po Shek Wu Road Interchange (Roundabout) • J9 – Po Wan Road / San Po Street (Signal Junction) • J10 – San Wan Road / San Po Street (Priority) • J11 – Choi Yuen Road / Choi Fai Street (Priority) • J12 – Choi Fat Street / Choi Fai Street (Priority) • J13 – Ka Fu Close / San Po Street (Priority) • J14 – Ka Fu Close / Cheuk Wan Street (Priority) • L1 – Po Shek Wu Road – Section between (Link) Choi Yuen Road and Fanling Highway • L2 – Po Shek Wu Road – Section between (Link) Choi Yuen Road and Po Wan Road • L3 - Po Shek Wu Road – Section between (Link) Jockey Club Road and Po Wan Road • L4 - Po Wan Road (Link) • L5 – San Wan Road (Link) • L6 – Choi Fat Road (Link) • L7 – Choi Yuen Road (Link)

2.3.2 The traffic counts were undertaken on a normal weekday in 2016 during the periods 0730 - 0930 and 1730 - 1930 hours. Supplementary survey was conducted in May 2017 at Junctions J6, J7, J8 and Link L1. The surveyed traffic flows in 2017 are in general higher than those of 2016. It is revealed that the observed total flows of the most critical road links in the town, i.e. Po Shek Wu Road and So Kwun Po Road, in 2017 is

236072-09 | Revision 14 | March 2021 Page 6 \\HKGNTS69\TRAFFIC_GROUP\DOCUMENT\236000\236072-09 INSTRUCTION NO. A19, TRAFFIC IMPACT ASSESSMENT FOR SITES 1 & 2 AT FANLING SHEUNG SHUI AREA 30\09 REPORTS\TIA\FORMAL\14TH FORMAL (02102020)\FR_REV13C.DOCX

Hong Kong Housing Authority Proposed Public Housing Development Sites 1 & 2 in Sheung Shui Areas 4 and 30 Traffic Impact Assessment

about 14% and 10% higher than those of 2016 during AM and PM peak hours respectively. In view thereof, adjustment factor of 1.14 (for AM peak) and 1.10 (for PM peak) to the traffic flows observed in 2016 is therefore applied for assessment of existing traffic condition, except for Junction J6, J7, J8 and Link L1 in which the observed traffic flows in 2017 are adopted. The adopted traffic flows to assess 2017 existing junction performance are presented in Figure 3. From the observed traffic flows in 2017, the morning and evening peak hours were identified as 0730-0830 hours and 1730-1830 respectively. In general, the morning peak hour flows were observed to be higher than the evening peak periods. 2.3.3 Junction and link capacity analyses have been carried out at the key junctions and links along the key access routes of the Sites. Results of the capacity assessment are shown in Tables 2.1 and 2.2 below. Table 2.1 Year 2017 Existing Junction Performance Performance (2) Junction (1) Type AM PM J1 Jockey Club Road / Po Shek Wu Road Roundabout 0.36 0.44 J2 Po Shek Wu Road / Po Wan Road Signal 29% 19% J3 Po Shek Wu Road / Choi Yuen Road Signal 4% 7% J4 Choi Yuen Road / Pak Wo Road Roundabout 0.47 0.43 J5 Jockey Club Road / Lung Sum Avenue Signal 14% 17% J6 Jockey Club Road / So Kwun Po Road Signal 12% 37% J7 So Kwun Po Road Interchange (3) Roundabout 0.96 0.92 J8 Po Shek Wu Road Interchange (4) Roundabout 0.96 0.99 J9 Po Wan Road / San Po Street Signal >100% >100% J10 San Wan Road / San Po Street Priority 0.24 0.16 J11 Choi Yuen Road / Choi Fai Street Priority 0.28 0.15 J12 Choi Fat Street / Choi Fai Street Priority 0.16 0.07 J13 Ka Fu Close / San Po Street Priority 0.03 0.05 J14 Ka Fu Close / Cheuk Wan Street Priority 0.07 0.05 Notes: (1) Please refer to Figure 1 for the location of the assessed junctions; and (2) Figures shown represent “Reserve Capacity” (RC) for the signal controlled junctions and “Design Flow to Capacity” (DFC) ratio for the priority junctions and roundabouts. A signal-controlled junction with a reserve capacity (RC) of 0% implies that it is operating at capacity while a negative RC suggests that the junction is overloaded. RC >= 15 % implies that the signal-controlled junction is operating satisfactory. For roundabout, the performance indicator is the DFC. DFC ratio of 1.00 indicates continual queuing and could not be considered acceptable. A DFC ratio of 0.85, indicating that queuing would theoretically be avoided in 85% of cases, can be considered reasonable. A DFC of 0.70 indicates that queuing will be avoided in 0.95 of cases. (3) Vehicular traffic queue was observed along Po Shek Wu Road Southbound during AM and PM peak hours. In general, the end of traffic queue was observed near Choi Yuen Road (i.e. Junction J3 - Po Shek Wu Road / Choi Yuen Road) which is about 350m in length from Junction J8 – Po Shek Wu Road Interchange. (4) Vehicular traffic queue was observed along So Kwun Po Road Southbound during AM and PM peak hours. In general, the end of traffic queue was observed near Jockey Club Road (i.e. Junction J6 - Jockey Club Road / So Kwun Po Road) which

3.4.10 In addition, a possible footbridge connection connecting the existing footbridge to Sheung Shui MTR Station would be provided subject to further investigation at detail design stage. Figure 15 shows the overview of the proposed footbridge network in the vicinity of the subject site.

3.5 Re-provision of Private Car Parking Space 3.5.1 Separate parking study was conducted in 2016 to review the parking condition in vicinity of the proposed developments, it was observed that there would be shortfall in about 270 nos. of private car parking spaces after closure of the affected public car parks under STT (currently providing about 470 nos. of car parking spaces) as mentioned in Section 3.1.2. 3.5.2 Permanent re-provision of private car parking space will be provided in the new car park block at Site 2, providing about 320 nos. of private car parking spaces. 3.5.3 During the construction stage of proposed development and the new car park block which is planned to be commenced in 2021/22, 300 nos. of private car parking spaces will be temporarily provided at portion of Site 1 and/or Site 2 under STT. Construction work at this portion of Site 1 and/or Site 2 will be commenced after the operation of the new car park block at Site 2 targeted in 2024/25. In conclusion, at least 300 nos. of private car parking space will always be provided during and after the construction works. 3.5.4 For goods vehicle parking, HKHA already suggested LandsD and relevant departments to make new STT sites and convert the existing STT car parks for goods vehicles and coach/bus parking only, in order to provide additional parking provision for large vehicles after closure of the concerned STT Car Parks for tackling the public car park issue in short term. For long term solution, it will be explored in the upcoming Phase 2 study of Sheung Shui Areas 4 and 30 pending the findings of Phase 1 Study.

4 FUTURE TRAFFIC CONDITIONS

4.1 Assessment Scenarios 4.1.1 To evaluate the associated traffic impact likely to be induced by the proposed change in land use, four scenarios were analysed and compared. The 1st and 3rd scenarios are Reference Scenario (without the proposed housing developments) in Year 2030 and 2033. The 2nd and 4th scenarios are Design Scenarios (with the proposed housing developments) in Year 2030 and 2033, respectively. 4.1.2 Taking into consideration that the proposed development will be completed by 2029/2030 and phased commissioning of NDA development area and Fanling Bypass, years 2030 and 2033 were adopted as the design years in the study. The year 2030 scenario would demonstrate the traffic conditions in the study area after completion of the proposed development. The year 2033 scenario would demonstrate the traffic conditions in the study area 3 years after completion of the proposed development respectively, taking into account of the change of traffic pattern before/ after the phased commissioning of NDA development area and Fanling Bypass. 4.1.3 Four assessment scenarios were assessed for the design years, namely: • 2030 Reference Case (2030 Background Traffic Flows including generated/attracted traffic related to other planned developments in the vicinity) • 2030 Design Case (2030 Reference Case Traffic Flows + generated/attracted traffic related to the proposed development) • 2033 Reference Case (2033 Background Traffic Flows including generated/attracted traffic related to other planned developments in the vicinity) • 2033 Design Case (2033 Reference Case Traffic Flows + generated/attracted traffic related to the proposed development) 4.1.4 The methodology adopted to forecast the traffic for the future years is presented in the next section. 4.1.5 The forecasted traffic flows for above assessment scenarios are shown in Figures 5 to 8.

4.2 Forecasting Methodology Proposed Area of Influence (AOI) 4.2.1 Area of Influence (AOI) is proposed and presented in Figure 1. It covers the critical road junctions and road networks in Sheung Shui Town, which may be affected by the proposed development in the Site. Necessary data and information within the AOI have been collected and assembled for assessments. New Development Area (NDA)

236072-09 | Revision 14 | March 2021

Hong Kong Housing Authority Proposed Public Housing Development Sites 1 & 2 in Sheung Shui Areas 4 and 30 Traffic Impact Assessment

4.2.2 Considering the traffic impact of the future development at New Development Area (NDA), it is expected that the future traffic patterns (i.e. design years 2030 and 2033) will be complex by the changes in the NDA. The complexity of growth in overall transport demand, coupled with the anticipated significant changes in pattern, would complicate the future traffic forecast. To maintain accuracy, it is recommended that comprehensive traffic forecast should be adopted, taking into account of the latest development proposal of NDA and the future road network and highway for the Year 2030 and Year 2033 traffic. Other Planned/Committed Developments in the Vicinity of Site 4.2.3 Besides NDA, there are some other planned/committed developments in the vicinity of the Sites, including: • Proposed Committed Public Housing Development at Po Shek Wu Estate; • Proposed Public Housing Development at Po Shek Wu Road, Sheung Shui; • Proposed Wholesale Conversion into Retail Development from Existing Advanced Technology Centre at No.2 Choi Fat Street, Sheung Shui; • Proposed Wholesale Conversion into Office-cum-Retail Building from Existing Industrial Building at No.9 Choi Yuen Road, Sheung Shui; • Proposed Wholesale Conversion into Retail Development at No. 6 Choi Fai Street, Sheung Shui; and • Proposed Wholesale Conversion into Office-cum-Retail Building at No. 21 Po Wan Road, Sheung Shui 4.2.4 The estimated trips of these developments have also been reviewed and incorporated into the development of traffic forecast, as appropriate. Trip generation / attraction by proposed housing development of Po Shek Wu Estate are reference to the HKHA’s Traffic Impact Assessment (TIA) Report for Po Shek Wu Estate. Trip generation / attraction of Site at Po Shek Wu Road are estimated from trip generation rates of public housing development stipulated in TPDM as shown in Table 4.1. Summary of the trip generation of these public housing developments is given in Table 4.2 respectively.

The upper tier involved the use of Arup’s in-house CTS-compatible Traffic Model (TM) which produced traffic forecasts on a strategic basis. The cordoned matrices from the TM would then be input into the lower tier Local Area Traffic Model (LATM) which would be used to predict the future year traffic flow on a more local perspective. The modelling approach is elaborated in the following sections. Upper Tier Model 4.2.7 Arup’s in-house CTS-compatible TM was applied as the upper tier model. The TM was capable of producing trip matrices for the base and future years throughout the territory. The TM also offered the advantage of being capable of reflecting the traffic impacts especially the mode choice caused due to changes of road networks. It was hence recommended to adopt this model as the basis, and updated using the latest available planning data in the Enhanced 2011-based Territorial Population and Employment Data Matrix (TPEDM), planned and committed new infrastructures and local developments, including private development at Castle Peak Road – Kwu Tung (Rezoning Application No. Y/FSS/14), private development at Pak Wo Road 5

(Rezoning Application No. Y/FSS/13), public housing development at Sheung Shui Area 36 Phase 4 (Ching Ho Extension), Kong Nga Po Police Facilities and Sandy Ridge Columbarium and Crematorium Development for this study. 4.2.8 In order to ensure the traffic patterns predicted by the model could reasonably replicate the current traffic condition and hence provided confidence in forecasting the future year traffic, the output from the base year TM was compared against observed traffic flows as published in the Annual Traffic Census for both the AM and PM peak hours. Lower Tier Model 4.2.9 Matrices cordoned from the TM were input into the LATM. Despite the LATM only performs traffic assignment, it offered the benefit of giving more detailed accounting of queuing, junction control and delays, making it more suitable for the evaluation of localized traffic impacts. 4.2.10 The development of the LATM would follow the same approach as TD’s latest 2008-based Base District Traffic Model (BDTM). The compatibility between the 2 tiers was ensured by the control of the external trip ends, which were essentially the link flows of Fanling Highway, Fan Kam Road, Castle Peak Road – Kwu Tung, obtained from the TM. The link flows and junction turning counts on a more local level would be produced by the LATM assignments for subsequent impact assessments. 4.2.11 Validation was also carried out for the LATM and additional focus was given to the comparison of observed and modelled flows at both strategic and local road links. Supplementary traffic survey had been conducted to provide traffic flows and turning counts which were not available in the Annual Traffic Census. 4.2.12 As survey counts represented the Year 2017 observed traffic flows, it was proposed to adopt Year 2017 as the LATM base year, and the LATM was validated to Year 2017 conditions. 4.2.13 The LATM has been developed for the area of N.T. North District, in which the traffic condition could be fully represented. Trip Generation / Attraction for Proposed Public Housing Development of Sites 1 and 2 at Sheung Shui Areas 4 and 30 4.2.14 For the proposed development trip generation and attraction, trip rates were made reference to Transport Department’s Transport Planning and Design Manual (TPDM) Volume 1 Chapter 3 - Transport Considerations in Town Plans. The adopted trip rates for the proposed development are shown in Table 4.4.

The traffic generation surveys were undertaken during AM & PM peak hours on a normal weekday. The observed peak traffic generation rates are tabulated in Table 4.5. Table 4.5 Summary on Surveyed Trip Rates at Existing Public Housing Development in North District AM Peak PM Peak Development Generation Attraction Generation Attraction Wah Ming Estate – 5,340 flats 0.0171 0.0125 0.0073 0.0127 (pcu/flat/hr) Ching Ho Estate – 7,200 flats 0.0175 0.0085 0.0078 0.0158 (pcu/flat/hr)

4.2.16 For public housing development, it is observed that the surveyed trips rates for both AM and PM peaks shown in Table 4.5 are much lower than the mean values of rate stated in TPDM according to Table 4.4. It is therefore recommended to adopt the mean values of rate stated in TPDM for conservative assessment purpose. 4.2.17 For Site 1, there are about 2,088 flats in the public housing development, 395 sqm GFA of retail facilities, 10,513 sqm GFA of social welfare facilities, 886 sqm GFA of kindergarten. To adopt a conservative approach for the subject planned housing sites, a 10% increase in flat number (i.e. 2,297 flats) is adopted for estimating the traffic generated / attracted by the development for traffic impact assessment purpose. For the kindergarten and welfare facilities in the Site, a nominal traffic of total 30 pcu/hr each way is assumed for these facilities, since they are expected to induce minimal trips on the road network. 4.2.18 For Site 2, there are about 1,556 flats in the public housing development, 700 sqm GFA of retail facilities and a public car park in the Site. To adopt a conservative approach for the subject planned housing sites, a 10% increase in flat number (i.e. 1,712 flats) is adopted for estimating the traffic generated / attracted by the development for traffic impact assessment purpose. On the other hand, as the subject site

236072-09 | Revision 14 | March 2021

Hong Kong Housing Authority Proposed Public Housing Development Sites 1 & 2 in Sheung Shui Areas 4 and 30 Traffic Impact Assessment

is currently a public car park (providing about 470 nos. of private car parking space), the proposed future car park (providing about 320 nos. of private car parking space) should not induce additional increase of traffic in view of the similar use as existing facilities. It is also considered to be conservative in view of the smaller scale of the proposed car park compared with the existing car park. On the other hand, as the traffic generated / attracted from/to the post office are expected to fall outside the peak hours and would be minimal during the peak hours, the traffic from these facilities are neglected in the assessment. 4.2.19 The traffic generation by the proposed development are summarised in Table 4.6. The total trips would be around 255 and 224 two-way pcus/hr during the AM and PM peak periods respectively.

Improvement measures are proposed and discussed in succeeding sections.

4.4 Proposed Junction Improvement Schemes Proposed Junction Improvement of Junction J2 – Po Shek Wu Road / Po Wan Road, J3 - Po Shek Wu Road / Choi Yuen Road, J5 - Jockey Club Road / Lung Sum Avenue and J8 - Po Shek Wu Road Interchange 4.4.1 Under the CEDD’s project “Site Formation and Infrastructure Works for Police Facilities in Kong Nga Po” (hereafter named Kong Nga Po Project), junction improvement schemes are proposed in North District, including J2 – J/O Po Shek Wu Road / Po Wan Road, J3 - Po Shek Wu Road / Choi Yuen Road, and J5 - Jockey Club Road / Lung Sum Avenue and J8 - Po Shek Wu Road Interchange. The site formation and infrastructure works, with the corresponding proposed junction improvement works, are tentatively be completed before the population intake year of the subject development under the current available information, while the junction improvement work will be implemented under NDA project as confirmed by CEDD. 4.4.2 The details of the proposed junction improvement schemes are summarized as follows. The general layout of the proposed junction improvement scheme is shown in Appendix B:

236072-09 | Revision 14 | March 2021

Hong Kong Housing Authority Proposed Public Housing Development Sites 1 & 2 in Sheung Shui Areas 4 and 30 Traffic Impact Assessment

Junction J2 – Po Shek Wu Road / Po Wan Road 4.4.3 Under the Kong Nga Po Project, the improvement scheme will mainly include the modification of lane configurations at Po Shek Wu Road and Po Wan Road: a) Lane arrangement of Po Shek Wu Road southbound to be revised for allowing straight-ahead traffic to use three traffic lanes; and b) Lane arrangement of Po Wan Road eastbound to be revised for allowing right-turn traffic to use two traffic lanes c) Local widening of Po Shek Wu Road southbound from 2 to 3 lanes 4.4.4 However, the junction J2 would still be operating close to capacity with the above improvement scheme in place. Thus, the following further enhancement is proposed under this study for implementation in Year 2030 and 2033, and to be implemented by the NDA project. HKHA will closely liaise with the NDA project on the details of the junction improvement scheme in later design stage, in order to implement the junction improvement scheme before population intake of the proposed public housing development: a) Lane arrangement of Po Shek Wu Road northbound to be revised for allowing left-turn traffic to use two traffic lanes; and b) Local widening of Po Wan Road westbound from 1 to 2 lanes Junction J3 - Po Shek Wu Road / Choi Yuen Road 4.4.5 The improvement scheme will include local widening of Po Shek Wu Road northbound to allow straight-ahead traffic to use three traffic lanes. Junction J5 - Jockey Club Road / Lung Sum Avenue 4.4.6 The improvement scheme will include widening of Jockey Club Road and Lung Sum Avenue: a) Local widening with one additional straight-ahead traffic lane on Jockey Club Road eastbound b) Local widening with one additional straight-ahead traffic lane on Lung Sum Avenue northbound Junction J8 – Po Shek Wu Road Interchange 4.4.7 The improvement scheme will include local widening of the entry arm of Fanling Highway westbound slip road from existing two lanes to three lanes. The widening works is not at the critical arm of the roundabout and will not result in changes in Design Flow to Capacity (DFC). However, the local widening of entry arm will enhance the left- turn traffic to Fan Kam Road southbound by increasing the available queuing length for traffic entering the circulation lanes of the interchange. Proposed Junction Improvement of J6 - Jockey Club Road / So Kwun Po Road

236072-09 | Revision 14 | March 2021

Hong Kong Housing Authority Proposed Public Housing Development Sites 1 & 2 in Sheung Shui Areas 4 and 30 Traffic Impact Assessment

4.4.8 Junction improvement schemes at J6 - Jockey Club Road / So Kwun Po Road are being reviewed and explored under NDA, which includes: a) Lane arrangement of the Jockey Club Road northbound to be revised for allowing left-turn traffic to use two traffic lanes; and b) Method-of-Control (MOC) to be revised for minimizing / optimizing the intergreen time c) Lane arrangement of Ma Sik Road southbound to be revised for allowing three traffic lanes for vehicles to travel straight ahead d) Local widening of So Kwun Po Road southbound from 2 to 3 lanes 4.4.9 However, the junction J6 would still be operating over capacity with the above improvement scheme in place in both Year 2030 and 2033. Thus, the following further enhancement is proposed under this study for implementation: a) Local widening with one additional straight-ahead traffic lane on So Kwun Po Road northbound b) Local widening of Ma Sik Road northbound from 2 to 3 lanes 4.4.10 HKHA will closely liaise with the NDA project on the details and implementation of the junction improvement scheme. 4.4.11 The general layout of the proposed junction improvement scheme is shown in Appendix B. 4.4.12 With the above proposed junction improvement schemes in place, the results of junction capacity assessment of Junctions J2, J3, J5, J6 and J8 are shown in Table 4.12 below: Table 4.12 Summary of Junction Performance – With Proposed Junction Improvement Schemes in Place Junction Performance (2) Year 2030 Year 2033 Junction (1) Type Reference Case Design Case Reference Case Design Case AM PM AM PM AM PM AM PM Po Shek Wu Road / J2 Signal 22% 17% 17% 15% 19% 13% 14% 11% Po Wan Road Po Shek Wu Road / J3 Signal 18% 17% 15% 13% 16% 15% 13% 11% Choi Yuen Road Jockey Club Road / J5 Signal 21% 53% 18% 51% 19% 51% 16% 49% Lung Sum Avenue Jockey Club Road / J6 Signal 12% 27% 11% 27% 10% 25% 9% 25% So Kwun Po Road Po Shek Wu Road Round J8 0.78 0.75 0.82 0.77 0.80 0.76 0.83 0.78 Interchange (3) about Notes: (1) Junction Improvement Scheme had been incorporated in both reference and design case; and (2) Figures shown represent “Reserve Capacity” (RC) for the signal controlled junctions and “Design Flow to Capacity” (DFC) ratio for the roundabout. A signal-controlled junction with a reserve capacity (RC) of 0% implies that it is

236072-09 | Revision 14 | March 2021

Hong Kong Housing Authority Proposed Public Housing Development Sites 1 & 2 in Sheung Shui Areas 4 and 30 Traffic Impact Assessment

operating at capacity while a negative RC suggests that the junction is overloaded. RC >= 15 % implies that the signal-controlled junction is operating satisfactory. For roundabout, the performance indicator is the DFC. DFC ratio of 1.00 indicates continual queuing and could not be considered acceptable. A DFC ratio of 0.85, indicating that queuing would theoretically be avoided in 85% of cases, can be considered reasonable. A DFC of 0.70 indicates that queuing will be avoided in 0.95 of cases. (3) The proposed widening works is not at the critical arm of the roundabout and thus does not result in changes in Design Flow to Capacity (DFC). 4.4.13 With the proposed junction improvement scheme in place, performance of all junction would be improved with RC higher than those before the proposed housing developments in place (i.e. Reference Case as presented in Tables 4.8 and 4.10). HKHA will closely liaise with the relevant government departments on the details of the junction improvement scheme in later design stage, in order to implement the junction improvement scheme before population intake of the proposed public housing development. HKHA will consider taking up the junction improvement works at J2 and J3 as described in Section 4.4.4 and 4.4.5 respectively, in which the traffic generated/attracted by the proposed housing development have direct impact to these junctions, by government funding in case the junction improvement works undertaken by others could not meet HKHA's population intake of the proposed housing development. 4.4.14 The proposed road improvement works under Kong Nga Po project by CEDD would be implemented under NDA project by CEDD as confirmed by CEDD.

4.5 Proposed Improvement Scheme at Po Shek Wu Road 4.5.1 To further enhance the vehicular accessibility in the vicinity of the proposed housing sites and alleviate the existing traffic queue problem on Po Shek Wu Road southbound, an improvement scheme at Po Shek Wu Road Southbound is shown in Figure 9. The improvement scheme consists of widening the Po Shek Wu Road Southbound (Section between Fanling Highway and Choi Yuen Road) with 1 no. of additional lane. 4.5.2 As mentioned in Section 2.4, Po Shek Wu Road Interchange is currently operating close to its capacity, mainly due to high traffic volume from Po Shek Wu Road Southbound approach arm. Due to the short available queuing length for vehicles waiting to enter the interchange, the left-turn traffic to Fanling Highway Eastbound would frequently be hindered from the vehicle queue at the interchange. Vehicles would easily queue up along Po Shek Wu Road Southbound, reaching Choi Yuen Road (i.e. Junction J3 - Po Shek Wu Road / Choi Yuen Road), and further extend to Po Wan Road (i.e. Junction J2 - Po Shek Wu Road / Po Wan Road) at intermittent critical condition. 4.5.3 The proposed improvement scheme will widen Po Shek Wu Road Southbound to 3 nos. of lanes all the way. This could accommodate an

236072-09 | Revision 14 | March 2021

Hong Kong Housing Authority Proposed Public Housing Development Sites 1 & 2 in Sheung Shui Areas 4 and 30 Traffic Impact Assessment

additional lane with approximately 300m in length. The total available length of traffic lanes for queueing at existing condition and after implementation of the proposed improvement scheme are summarized in Table 4.13. Table 4.13 Summary of Available Length of Traffic Lanes for Queuing of Po Shek Wu Road Southbound (Section between Po Shek Wu Road Interchange and Choi Yuen Road) Available Length of Traffic Lanes for Queuing (m) With Possible Improvement Scheme Location Existing in Place (2 lanes) (3 lanes) Po Shek Wu Road Southbound (Section between Po Shek Wu Road ~600 ~850 Interchange and Choi Yuen Road) 4.5.4 The traffic entering the interchange could utilize either middle or right lane, and the traffic to Fanling Highway Eastbound can enter the dedicated left-turn lane by utilizing the additional lane at Po Shek Wu Road Southbound. It is anticipated that the traffic condition at Po Shek Wu Road Southbound could be improved by minimizing the weaving movements and increasing the queuing length. 4.5.5 CEDD Civil Engineering Office will undertake the improvement of Po Shek Wu Road. The implementation details, design and construction responsibility will be further investigated in the later design stage. 4.5.6 With the proposed Po Shek Wu Road widening scheme in place, the results of link capacity assessment of Link L1 – Po Shek Wu Road southbound (Section between Choi Yuen Road and Fanling Highway) for Year 2030 and 2033 are summarized in Table 4.14 and 4.15 respectively.

4.5.8 It is worth to note that the future Po Shek Wu Interchange Improvement which provides a flyover to allow the right turning traffic from Po Shek Wu Road southbound to Fanling Highway westbound and bypass the existing Po Shek Wu Interchange. The traffic flow on Po Shek Wu Road southbound, between Choi Yuen Road and Fanling Highway, will be reduced and the traffic queue problem is expected to be further alleviated.

4.6 Other Improvement Schemes to Existing Interchanges 4.6.1 Besides the future Po Shek Wu Interchange Improvement, it is noted that the government is planning to carry out a feasibility study for a new infrastructure connecting the northern and southern side of Fanling Highway. The new North South Link will be able to divert traffic and relieve the traffic condition in the existing interchanges, i.e. Junctions J7 – So Kwun Po Road Interchange and J8 –Po Shek Wu Road Interchange. 4.6.2 Table 4.16 summarizes the improvement scheme as proposed amongst different concurrent projects.

5 SENSITIVITY TEST

5.1 Sensitivity Test for Proposed Public Transport Interchange at Site 1 5.1.1 As discussed in the Section 4.3, Junction J7 – So Kwun Po Road Interchange would be operating at DFC slightly over 1.0 in Years 2030 and 2033. For long-term, the new North South Link as discussed in Section 4.6.1 will be able to divert traffic at J7. As J7 is a critical junction, short term measures should also be proposed to improve the condition as far as possible. In view thereof, it is proposed to provide a new public transport Interchange (PTI) at Site 1 to facilitate redistribution of public transport routes. It will thus reduce the amount of public transport passing through J7 and relieve the traffic condition. Around 100 pcu/hr of public transport is assumed to be diverted away from J7 and redistribute to J3 – Po Shek Wu Road / Choi Yuen Road and J4 – Choi Yuen Road / Pak Wo Road. Figure 10 shows an example of public transport routing before and after public transport redistribution. The exact junction performance will be subject to public transport rerouting to be planned. 5.1.2 Below Table 5.1 shows the junction capacity assessment after public transport redistribution for Year 2030 and 2033. Table 5.1 Junction Performance Before and After Public Transport Redistribution Junction Performance (2) Year 2030 Design Case Year 2033 Design Case Junction (1) Before Public After Public Before Public After Public Transport Transport Transport Transport Redistribution Redistribution Redistribution Redistribution AM PM AM PM AM PM AM PM Po Shek Wu Road / J3 15% 13% 3% 8% 13% 11% 2% 7% Choi Yuen Road Choi Yuen J4 Road / Pak 0.48 0.44 0.55 0.48 0.49 0.44 0.56 0.49 Wo Road So Kwun J7 Po Road 1.04 1.02 0.99 0.98 1.04 1.02 0.99 0.98 Interchange Notes: (1) Please refer to Figure 1 for the location of the assessed junctions; and (2) Figures shown represent “Reserve Capacity” (RC) for the signal controlled junctions and “Design Flow to Capacity” (DFC) ratio for the roundabout. A signal-controlled junction with a reserve capacity (RC) of 0% implies that it is operating at capacity while a negative RC suggests that the junction is overloaded. RC >= 15 % implies that the signal-controlled junction is operating satisfactory. For roundabout, the performance indicator is the DFC. DFC ratio of 1.00 indicates continual queuing and could not be considered acceptable. A DFC ratio of 0.85, indicating that queuing would theoretically be avoided in 85% of cases, can be

236072-09 | Revision 14 | March 2021

Hong Kong Housing Authority Proposed Public Housing Development Sites 1 & 2 in Sheung Shui Areas 4 and 30 Traffic Impact Assessment

considered reasonable. A DFC of 0.70 indicates that queuing will be avoided in 0.95 of cases. 5.1.3 J7 will be improved with DFC reduced from 1.04 to 0.99 at the critical AM peak of Year 2030 and 2033, while J3 and J4 will still be operating within capacity, after public transport redistribution. 5.1.4 It is suggested to conduct a comprehensive review when the traffic condition becomes stable after commissioning of the Lung Shan Tunnel which will commission in end 2018 and cause changes in the traffic pattern in Fanling/Sheung Shui.

5.2 Sensitivity Test on the Programme Slippage of Major Improvement Works 5.2.1 This sensitivity test will investigate the impact on the surrounding road network in case of slippage of the major improvement works, i.e. Fanling Bypass (Eastern Section), for the 2030 Design Case Scenario. Other local junction improvement schemes considered for the 2030 Design Case Scenario as stated in Table 4.16 are scheduled to be completed by Year 2023/24, which are unlikely to be postponed beyond the population intake of the subject development. Therefore, the local junction improvement schemes are assumed to be in place in this sensitivity test. The sensitivity test also considers the public transport redistribution as described in Section 5.1. 5.2.2 The sensitivity test scenario will exclude Fanling Bypass (Eastern Section) from the Base Design Case Scenario to reflect any programme slippage. Fanling North NDA (Advance Phase) will also be excluded. 5.2.3 Table 5.2 compares the assumptions considered in the Base Design Case Scenario and in the sensitivity analysis.

It is revealed that all key junctions in Sheung Shui area will still be operating with DFC < 1.0 or RC > 0% and considered acceptable.

6 PEDESTRIAN TRAFFIC IMAPCT ASSESSMENT

6.1 Existing Pedestrian Conditions 6.1.1 Pedestrian count surveys were conducted on normal weekdays in September 2016 / February & April 2017 at selected locations during the periods 0700-1000 and 1700-2000 hours. These locations of the surveyed pedestrian facilities are detailed in Figure 11 and summarized in Table 6.1. Table 6.1 Critical Pedestrian Facilities Index (1) Type I Footpath K Footbridge L Footbridge M Staircase O Footpath Q Footpath R Subway S Subway T Staircase AE Footbridge AF Staircase AH Footpath AI Staircase AK Footbridge AL Staircase AM Footbridge AN Footpath AO Staircase AT Footbridge BA Footpath BB Footpath BC Footpath BD Footpath BF Crossing BG Footpath Note: (1) Refer to Figure 11 for the location of the assessed pedestrian facilities. 6.1.2 It was observed that the peak pedestrian period was occurred in the morning peak during 0830 – 0930 and evening peak during 1745 - 1845. ‘Level of Service’ and “volume to capacity ratio (V/C)” assessment have been undertaken.

236072-09 | Revision 14 | March 2021

Hong Kong Housing Authority Proposed Public Housing Development Sites 1 & 2 in Sheung Shui Areas 4 and 30 Traffic Impact Assessment

Level of Service (LOS) 6.1.3 ‘Level of Service’ (LOS) analysis of the existing pedestrian facilities was carried out based on the definitions presented in the Highways Capacity Manual 2000. This follows the approach currently being recommended by Transport Department. In general, LOS C and D are typical values and LOS A and B would provide a very good LOS. At a LOS of A, pedestrians basically move in desired paths without altering their movements in response to other pedestrians. Walking speeds are freely selected and conflicts between pedestrians are unlikely. At a LOS of B, pedestrians would continue to freely select their own walking speed, can bypass slower pedestrians, and avoid crossing conflicts with others. At a LOS of C, pedestrians are restricted in selecting walking speed and in bypassing other pedestrians. A LOS of D would represent a further deterioration of the pedestrian movements but would still provide reasonable fluid flow. At a LOS of E or lower, it was determined that mitigation measures or improvement schemes should be considered to achieve a LOS of D or better. For the purposes of this pedestrian impact assessment, a LOS of C or above would be considered acceptable while a LOS of D would be marginally acceptable. Table 6.2 shows the various LOS ‘quantified’ in terms of pedestrian flow rates. Table 6.2 Level of Service (LOS) for Walkway Flow rate LOS Description (ped/min/m) Pedestrians move in desired paths. Walking speeds are freely selected and A <= 16 conflicts between pedestrians are unlikely. Sufficient space is provided for pedestrians to freely select walking speeds, B 16 - 23 to bypass other pedestrians and to avoid crossing conflicts with others. Pedestrians become aware of other pedestrians. Sufficient space is available to select normal walking speeds and to bypass C 23 - 33 other pedestrians in unidirectional stream. Minor conflicts will occur in reverse direction or crossing movements. Freedom to select individual walking speeds and bypass other pedestrians is restricted. Probability of conflicts is high in crossing or reverse-flow D 33 - 49 movements. LOS provides reasonable fluid flow, however, friction and interactions between pedestrians are likely to occur. All pedestrians would have normal walking speeds restricted. Space is insufficient to pass over slower pedestrians. Cross and reverse movements E 49 - 75 are possible only with extreme difficulties. Design volumes approach the limit of walking capacity. Walking speeds are severely restricted. Forward progress is made by shuffling. Cross and reverse movements are virtually impossible. Space is F > 75 more characteristic of queued pedestrians than of moving pedestrian streams.

6.2 Pedestrian Demand Forecasting Background Pedestrian Flows and Other Planned/Committed Developments in the Vicinity of Site 6.2.1 Pedestrian flows adopted in this study were primarily based on the existing Year 2016 pedestrian counts undertaken (details refer to Section 6.1). Pedestrian trip generation/attraction for other planned/committed developments in the vicinity of the Sites had been incorporated in the background pedestrian flows, including the following developments: • Proposed Committed Public Housing Development at Po Shek Wu Estate; • Proposed Public Housing Development at Po Shek Wu Road, Sheung Shui; • Proposed Wholesale Conversion into Retail Development from Existing Advanced Technology Centre at No. 2 Choi Fat Street, Sheung Shui; • Proposed Wholesale Conversion into Office-cum-Retail Building from Existing Industrial Building at No.9 Choi Yuen Road, Sheung Shui; • Proposed Wholesale Conversion into Retail Development at No. 6 Choi Fai Street, Sheung Shui; and • Proposed Wholesale Conversion into Office-cum-Retail Building at No. 21 Po Wan Road, Sheung Shui. 6.2.2 The estimated pedestrian trips of these developments have also been reviewed and incorporated into the development of pedestrian forecast, as appropriate. Pedestrian trip generation / attraction by proposed housing development of Po Shek Wu Estate are reference to the HKHA’s Traffic Impact Assessment (TIA) Report for Po Shek Wu Estate. To estimate the pedestrian generation for other planned/committed development in the vicinity of Site, reference has been made to in-house pedestrian survey conducted for the existing public housing developments, office, retail facilities and kindergarten. The trip rates were applied to the development parameters of the planned/committed development to derive the pedestrian trips as shown in Table 6.4.

Development Trip Generations 6.2.3 To estimate the pedestrian generation for the proposed development, reference has been made to in-house pedestrian survey conducted for the existing public housing developments, retail facilities and kindergarten school. The trip rates were applied to the proposed additional number of flats to derive the resident trips. These rates and the estimated pedestrian trips are tabulated in Table 6.5. For the development type of welfare facilities, they are expected to serve mainly the local residents and will only induce minimal pedestrian trips on the walkway network. These development types are therefore excluded from the estimation.

6.2.4 Trip rates of proposed housing development and kindergarten facilities had also been referenced to the traffic generation survey conducted at the similar development in North District. The traffic generation surveys were undertaken during AM & PM peak hours on a normal weekday. The observed peak traffic generation rates are tabulated in Table 6.6.

6.2.5 For public housing development and kindergarten, it is observed that the surveyed pedestrian trips rates for both AM and PM peaks shown in Table 6.6 are lower than the trip rates adopted for approved HKHA’s TIA Report of Po Shek Wu Estate stated in Table 6.5. It is therefore recommended to adopt the pedestrian trip rates adopted for HKHA’s TIA Report of Po Shek Wu Estate, for conservative assessment purpose. 6.2.6 As indicated in Table 6.5, the proposed development would generate some 3,046 and 1,211 pedestrians per hour during AM and PM peak hour period respectively. And the attraction would be some 1,220 and 2,468 pedestrians per hour during AM and PM peak hour respectively. The generated pedestrian demand would be superimposed onto the surrounding pedestrian facilities according to the observed trip distribution at the existing public housing site, to produce the future forecast pedestrian flows (i.e. Year 2030 upon completion of the Sites). 6.2.7 As mentioned in Section 3.4, a footbridge is proposed to connect the proposed development at Site 1 to Po Shek Wu Estate, with new footbridges connecting to Po Shek Wu Road Site and the existing footbridge linking Choi Yuk House on the south and Landmark North on the north. For Site 2, a footbridge is proposed to connect the proposed development to Po Shek Wu Road Site, with new footbridges connecting to Po Shek Wu Estate and the existing footbridge linking Choi Yuk House on the south and Landmark North on the north. The indicative alignment is shown in Figure 11. Their engineering feasibility should be reviewed by other civil and structural studies etc and subjected to detailed design stage. It is anticipated that some residents of the proposed development at the Sites 1 & 2 will be diverted to use the proposed comprehensive footbridge network. Examination of the pedestrian impacts on the existing pedestrian network due to the aforesaid new footbridges will be included in the pedestrian facilities assessment in the succeeding section.

Proposed Pedestrian Facilities Improvement Schemes by Other Projects 6.2.8 Under the TIA report of proposed Public Housing Development at Po Shek Wu Estate, location I will be operating over-capacity. Associated improvement measure has been proposed to alleviate the condition. Diversion of the existing cycle track via the adjacent cycle parking area was proposed to facilitate footpath widening at location I. The clear footpath width will be widen to 3m, taking into account of the provision of railing along road kerb. The existing cycle parking area will be modified with expansion of new cycle parking facilities to the western side, underneath the existing footbridge connecting Landmark North and Choi Yuen Estate. Below figure demonstrates the preliminary layout of the aforesaid diverted cycle track, modified cycle parking area and footpath widening at Location I.

(10) In view of the reduced surveyed pedestrian flows in Year 2016/2017 at locations I, O, AE, AN and AT compared with the Year 2014 surveyed pedestrian flows under the pedestrian assessment of Po Shek Wu Estate, the highest surveyed pedestrian flows among Year 2014 and Year 2016/2017 are adopted for pedestrian flow forecast as the conservative assessment purpose, with the aims of taking into account the fluctuation impacts of the parallel trade activities; (11) Taking into account of the bus passenger queue and reducing the effective footpath width by 1m, the flow rate of BH becomes 36.3 ppm/m and 49.0 ppm/m (i.e LOS D) during AM and PM peak respectively; and (12) Proposed footbridge between the existing footbridge and Sheung Shui MTR Station. Assume minimum 3m clear width to be adopted.

6.3.3 The pedestrian facilities with the proposed footbridge in place would be adequate to cater for the additional pedestrian demand generated from the proposed development, with LOS “C” or better, except for location AE and BH, under the future pedestrian facilities assessment. 6.3.4 It is worth to note that the proposed public housing developments would not induce significant impact to footbridge location AE, which is the footbridge connecting MTR Sheung Shui Station and Landmark North, and operating at LOS D. Site-related trip to/from these major attraction nodes could mainly use the at-grade footpaths and footbridges (i.e. locations L and AM) instead of AE. 6.3.5 In addition, with the additional footbridge FF provided along San Wan Road in place, location BH will marginally operate beyond LOS C and at low-end of LOS D. Site-related trip (i.e Site 2 and Po Shek Wu Road Site) to/from MTR Sheung Shui Station would be able to travel via FE and FF, instead of BH. Therefore, no improvement measures at BH is considered necessary if the proposed footbridge network is in place.

7.3 Review of Impact on East Rail Line 7.3.1 According to the Review and Update of the Railway Development Strategy 2000 - Executive Summary published by Highways Department, the future North South Corridor (formed by the East Rail Line, Lok Ma Chau Spur Line and Hung Hom to Admiralty Section of the Shatin to Central Link) will have a maximum carrying capacity of 80,000 persons per hour per direction. 7.3.2 According to the Public Transport Strategy Study published by Transport and Housing Bureau in June 2017, about 37% of public transport trips will use heavy rail, such that the proposed public housing development is expected to generate some additional 1,127 passengers one-way during the critical AM peak hour. The increase in passenger demand on the future North South Corridor is no more that 1.5% of its carrying capacity. Hence, the additional passenger demand on the future North South Corridor is considered negligible. 7.3.3 In addition, the future Northern Link (NOL) will connect the East Rail Line and the West Rail Line, forming a loop in the northern New Territories. This will allow residents in the New Territories to have more route choices without straining the road network. It is expected that NOL would reduce reliance on road-based transport and alleviating the associated congestion.

8 SUMMARY AND CONCLUSION

8.1 Summary 8.1.1 Arup was appointed by Hong Kong Housing Authority to conduct a Traffic Impact Assessment (TIA) for the land rezoning of the proposed public housing development at Sites 1 and 2 in Sheung Shui Areas 4 and 30 (the Sites). 8.1.2 Hong Kong Housing Authority intends to develop the Sites for public housing development with an approximate development schedule of 2,088 flats and 1,556 flats for Site 1 and Site 2 respectively. Full population intake will be by Year 2029/2030. 8.1.3 The parking and servicing facilities provision for the proposed development will be provided with reference to relevant standard and guideline. 8.1.4 To appreciate the existing traffic conditions, comprehensive classified traffic counts were conducted at the key junctions in the vicinity of the Site. Junction capacity analyses have been carried out at the key junctions in vicinity of the Site. Results of the analysis indicate that all assessed junctions are currently operating within capacity during both morning and evening peaks. 8.1.5 Junction capacity assessment was undertaken for scenarios of design years 2030 and 2033. All analysed results revealed that the associated junctions along the accessing/ leaving routes would still be performing within capacity, with proposed improvement work in place. 8.1.6 Future pedestrian condition was also assessed. A footbridge is proposed to connect the proposed development at Site 1 to Po Shek Wu Estate, with new footbridges connecting to Po Shek Wu Road Site and the existing footbridge linking Choi Yuk House on the south and Landmark North on the north. For Site 2, a footbridge is proposed to connect the proposed development to Po Shek Wu Road Site, with new footbridges connecting to Po Shek Wu Estate and the existing footbridge linking Choi Yuk House on the south and Landmark North on the north. The comprehensive footbridge network connecting different public housing developments will enhance the pedestrian accessibility. 8.1.7 Based on the LOS assessment, all assessed pedestrian facilities would be adequate to cater for the additional pedestrian demand generated from the proposed development, with LOS “C” or better, with proposed improvement schemes in place, except for locations AE and BH. Site- related trip to/from the major attraction nodes (e.g. MTR Sheung Shui Station and Landmark North) would mainly use the proposed footbridge network and not induce significant impact to locations AE and BH. Therefore, no improvement measure is considered necessary if the proposed footbridge network is in place. 8.1.8 A new PTI is proposed at Site 1 and the proposed Site 1 and Site 2 are located in the vicinity of major transport hubs i.e. MTR Sheung Shui Station / Landmark North Bus Terminus. Both Site 1 and Site 2 are

Hong Kong Housing Authority Proposed Public Housing Development Sites 1 & 2 in Sheung Shui Areas 4 and 30 Traffic Impact Assessment

served by various modes of public transport services in vicinity. In addition, provision of public transport facilities near the proposed development are proposed on San Wan Road.

8.2 Conclusion 8.2.1 Based on the above discussion, it is concluded that the proposed public housing development at Sites 1 and 2 in Sheung Shui Areas 4 and 30 (the Sites) would not induce adverse traffic impact on the surrounding road network and pedestrian network upon completion at design years 2030 and 2033. Therefore, the proposed development is considered acceptable with the timely implementation of the improvement works from the traffic point of view.
